Part #'s will depend on what length of shock you end up with..

For my truck on the rear I will use:
QA1 - TC1576P
OR
Rancho - RS99119

Bottom relocation Bracket - QA1 MT100K
Top relocation brackets - I had them laser cut and I have the autocad file for them. If there is enough interest I might run a batch for yall

I will post up pictures with I finish install

I did quite a bit of testing on mine and found that stiffining up the fronts help to prevent the truck from unloading the tires after the initial hit.

F2/R3= mid 1.7's spinning badly
F2/R4= mid to upper 1.6's initial hit on the tire was great with the front end coming up however the compression on the front shock was too weak allowing the frontend to come down too quickly. In slow mo it looked like the truck was hoping. Initial hit was good then it unloaded the tire and it spun for a bit.
F3/R4= mid 1.5's dead hook. Truck stopped bouncing the front end out of the hole. Just picked up the front nice and slow and let it back down nice and slow.

I rode a 4 on 6 for street duty. Didn't even notice the swaybar was missing and the ride was actually better than stock in my opinion.

Hope this helps.

They are custom cut. A local vendor laser cut them for me.

Thanks, I will give it a try.
I have the QA1 for the front already and my Rancho 9000 for the rear showed up yesterday.
I will give the ranchos a try and see how they do.
Then eventually I will try out the QA1's for the rear also.
